Sayyiduna Abu Huraira (may Allah be pleased with him) narrated: The Messenger of Allah (peace and blessings be upon him) forbade that a woman be married to a man who already has her paternal aunt in his wedlock, and likewise, that a woman be married to a man who already has her niece in his wedlock. And a woman should not be married to a man who already has her maternal aunt in his wedlock, nor should a maternal aunt be married to a man who already has her niece in his wedlock. And the younger should not be married while the elder is present, nor should the elder be married while the younger is present.
